I found a CT thread on exactly what you use from a while ago.
I seem to remember a popular copper coin product that was sold by a member here that suddenly was unavailable. Is this why?
Yes, it was for the removal of verdigris and worked very well
I still have some left and use it sparingly. I hope Thad or somebody else makes it again
Which is exactly why it should not be used.
Collectors learned the hard way over the course of decades that coating your coins with anything is a bad, bad, idea. And over those decades just about everything that can be thought of, has been thought of, and tried. It always turned out bad.
I wouldn't say to use it on all copper, but I would say this method is a method of conserving the surface conditions and color of early coppers that's been in practice a really long time. This technique and method puts a slight layer on the coin that keeps dust and contaminants from making direct contact with the copper.
it's really not so much a cleaning as it is putting on and reapplying a fine protective layer of oil to stop contaminants from making contact with the surface of the coin that may tone, spot or stain the surface. it's more maintaining and slowing the effects of time on the copper.
And Yeah, people say "never clean coins" and yet everyone dips to remove ugly toning, or uses acetone, or a hundred other things as they "conserve", the grading companies "conserve".
there's a right way and a wrong way to do things and "never clean coins" is a way to tell a novice that message, that unless they are confident in what they are doing, leave it up to an expert so as not to damage the coin. But mark my words just about everyone saying "never clean a coin" has done some cleaning and maybe still doing some cleaning to boot.
Starting to stray off the topic. I don't see anything wrong with the practice but practice the technique on common coins of low value of the same composition is what I'd tell you and in the end, they are your coins, you can do whatever you want with them.
Yep, they always say that. But there is a problem with what they say - the problem is - that isn't really what they mean. And some don't even realize it isn't what they mean - due to a lack of knowledge.
And some do mean it, but for those folks it's typically because they believe any and all forms of cleaning are bad.
I'm saying this for very simple reasons. For example, rinsing a coin in distilled water is cleaning the coin. Rinsing a coin acetone is cleaning the coin. Rinsing a coin in xylene is cleaning the coin. And, using coin dip on a coin is cleaning the coin. They are ALL cleaning the coin ! But, when done properly, not a single one of them will harm the coin in any way. And every single one of them is perfectly acceptable in the numismatic community, and has been for over 200 years !
So, if that's true, and it is, then what are these people talking about when they say "never clean coins" ? What they are talking about is to never harshly or improperly clean coins. And on that count they are correct - it is always bad !
But they don't say it that way when they are talking or writing. Instead they use the contraction of the correct terminology and say "clean/cleaning" when what they really mean is "harsh or improper clean/cleaning".
It is a habit that was started decades ago and continues to this day. Thus misinforming and miseducating thousands of collectors !
The proper cleaning of coins is a good thing, a very good thing ! It has protected and saved more coins for us than can be counted ! If it were not for proper cleaning then there would be tens of millions of coins that none of us could enjoy today ! The vast majority of all coins graded and slabbed by the TPGs have been properly cleaned ! And the TPGs themselves will even do it for you.
So to say - "never clean coins" - that's just about the worst, and most incorrect thing anybody could ever say !
